Abstract: A solar powered assisted trailer cooling system includes a trailer that has a bottom wall, a top wall and a perimeter wall attached to and extending between the top and bottom walls. The trailer is configured to be pulled by a vehicle to define a tractor trailer. A cooling assembly is mounted on the perimeter wall and is configured to cool an interior of the trailer. The cooling assembly includes a compressor powered by an electric motor. A plurality of solar panels converts sunlight into electricity. Each of the solar panels is mounted on an upper surface of the top wall. The plurality of solar panels is electrically coupled to a plurality of batteries. The solar panels recharge the batteries when the solar panels are producing electricity. The batteries are electrically coupled to the electric motor to power the compressor.
